Abstract

The utility model relates to a large handle for the lock, in particular to a large handle for the cylinder inserting type handing lock. The two sides of the gear ar provided with two racks which are parallel with opposite rack top; the root of the gear is provided with a convex tooth which can be meshed with the rack of one side; when the gear is rotated to a certain position and the two racks are not meshed, the large handle of the lock is arranged in the front and the rack will move upward to separate meshing through pressing the button of the large handle; then when the gear is rotated to another side to mesh with the rack, the axis will rotate to a reverse direction through pressing the button of the lock and the unlocking direction is changed without any tools. Therefore the utility model can overcome the disadvantages of the prior art.

Description

The big handle of a kind of lockset

Technical field: the utility model relates to the big handle of a kind of lockset, especially for the big handle of core-inset type hand holding lock on the security door.

Background technology: at present the pivot of door has and is installed in the left side, also have on the right of being installed in, this certainly will require safe-guard door lock also will a branch left side to drive with the right side to open, the existing core-inset type hand holding lock that is used on the security door comprises lock body, big handle of lockset and the big handle of Men Nei lockset outdoors, because the restriction of structure, in the door, the big handle of outer lockset can not exchange, promptly can not change the direction of unblanking after dispatching from the factory, this brings very big difficulty just for the formulation of the production schedule of producer, also cause overstocking of product easily, because will need lock and the right lock of opening that how many left sides open on their the there is no telling market, therefore urgent lockset of wishing to have a kind of direction of can the flexible transformation door lock unblanking.

Summary of the invention: the purpose of this utility model is to provide a kind of big handle of lockset that is used for the core-inset type hand holding lock on the security door for overcoming the deficiencies in the prior art, and the big handle of this lockset need not any instrument just can change the lockset direction of unblanking easily at any time.

For achieving the above object, the technical solution that the utility model adopts is as follows: the big handle of lockset still comprises the panel that has lockhole, the handle that bottom and panel are fixedly connected, vertically stretch to the flexible connection of Men Nei and lock body and be used to rotate the square shaft of opening the lock core mechanism that has dead bolt, be fixed with gear on the square shaft, gear and the tooth bar engagement of being located at a side, tooth bar is driven by the button of being located on the panel, the drive square shaft turns to open, it is characterized in that: described gear both sides respectively are provided with tooth bar respectively, two tooth bars are parallel and tooth top is relative, round week of Gear Root is provided with one section double wedge, this section double wedge once can only with the engagement of a side tooth bar wherein, and this gear when rotating to a certain position and two tooth bars all do not mesh.

Adopt the big handle of lockset of said structure, owing to be equipped with tooth bar in the both sides of gear, two tooth bars are parallel and tooth top is relative, round week of Gear Root is provided with one section double wedge, this section double wedge once can only with the engagement of a side tooth bar wherein, and when this gear rotates to a certain position and two tooth bars all do not mesh, therefore before installation, press the button of the big handle of lockset, move on the tooth bar and make the gear back that turns an angle break away from engagement, make gear rotation itself and this side tooth bar be meshed with the hand rotating shaft then, at this moment ought press the button of the big handle of lockset to opposite side and release button with tooth bar, the rotation direction reversed of square shaft has promptly reached the purpose that changes the direction of unblanking.

The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment simultaneously.

Description of drawings:

Fig. 1 is the utility model example structure side sectional view;

Schematic diagram when Fig. 2 meshes for wheel and rack;

Schematic diagram when Fig. 3 nibbles the bar separation for wheel and rack.

Specific embodiment: as shown in Figure 1, the big handle of the lockset of the present embodiment still is provided with panel 4, be stamped to form by stainless sheet steel, which is provided with lockhole 5, " Contraband " shape handle 6 one ends are fixed on the bottom of panel 4, also be provided with door open button 7 on the panel 4, button 7 is provided with a horizontal axis and is installed in formation moving seesaw-type structure on the panel, panel 4 is provided with the slide plate chamber 9 that the space forms between a square slide plate lid 8 that is stamped to form by iron plate and the base plate 1 by the inboard, be provided with one " Jiong " shape slide plate 3 in the slide plate chamber 9 movingly, thereby two column inboards of slide plate 3 are provided with double wedge constitutes tooth bar 2, slide plate 3 is formed by the tagger punching out, certain sliding space is left in slide plate chamber 9, the medial extremity of button 7 horizontal axis is chosen under the crossbeam that is inserted in " Jiong " shape slide plate 3, pressing button 7 can make slide plate 3 rise, " Jiong " shape slide plate 3 crossbeam upper center positions are provided with a spring and locate protruding 13, be provided with spring too on panel 4 inboard slide plate 3 glide directions and locate protruding 14, spring locatees protruding 13, being provided with back-moving spring 15 between 14 automatically resets button 7 and slide plate 3 at any time, gear 1 places between 3 liang of tooth bars 2 of " Jiong " shape slide plate, gear 1 center has square hole, offer circular hole on base plate 10 and the slide plate lid 8, square shaft 11 passes base plate 10 successively, gear 1 and slide plate lid 8 also extend outside the bottom 12, the tooth root diameter of a circle is slightly less than the distance between two tooth bars, 2 double wedges, only on 90 degree radians, be provided with double wedge on gear 1 circumference, with guarantee once can only with side tooth bar engagement, and turn 90 degrees the back and all do not mesh revolving with two tooth bars.

Before installation, inconsistent as unblank direction and security door of lockset, press the button 7 of the big handle of lockset, move on the tooth bar 2 and make gear 1 turn an angle back and tooth bar 2 disengaging engagements, rotating square shaft 11 with hand then makes gear 1 turn to opposite side and release button 7 that itself and this side tooth bar 2 is meshed, at this moment ought press the button 7 of the big handle of lockset, the rotation direction reversed of square shaft 11, after the big handle of lockset and lock body are installed on the security door, press the button 7 of the big handle of lockset, because the dead bolt shift length is limit in the lock body, the rotational angle of square shaft 11 drive move on the tooth bar 2 apart from deficiency so that gear 1 breaks away from engagement with tooth bar 2, remain and 2 engagements of this side tooth bar, promptly reached the purpose that changes the direction of unblanking.
